I don’t know what you mean by that being overblown. There is zero evidence that McConnell would even bring a nominee to vote if he’s majority leader again. It worked for him last time.
I don't think he would. He'd be replacing a liberal with another liberal, keeping it at a 5-3-1 split. At some point, these precedents catch up with a Party. A day will come (2024 or 2026?) when we have a Republican president and a Democrat Senate.
He’s already said that he would.

Well, that's in 2024. McConnell can at least stand by his "no confirmation in an election year if the President is of the opposite party" standard.
I think that's a lot harder to do if McConnell's majority wanted to run out the clock from January 2023 until January 2025.
I don’t think it would be difficult for McConnell at all. He both stalled confirmation for 9 months in 2016 and got one through in weeks, despite a pandemic requiring senators to quarantine, in 2020. If he could get the Court to 9-0, I’m quite sure he would.
He is undeniably unscrupulous and that has made him the most consequential politician of the 21st century (Trump's impact on democracy and tribal division notwithstanding). McConnell has done his job brilliantly if not at times shamelessly. For that, social conservatives are likely elated at the prospect of Mitch doing it again. No doubt that you are correct C2021, McConnell doesn't have a bone in his body that would cause him to think that there is a problem that SCOTUS massively overrepresents the social ideology of a segment of Americans.
The Supreme Court was not supposed to be this political, not that politics has never played a role, but all we need to do is look at the Senate votes for justices to see how it's only recently become the norm for opposition parties to unite against a nominee. Taking out Borke, Thomas, and Kavanaugh who were controversial, Kagan had 63 votes, Roberts had 78 votes, Sotomayor had 68. Moving back, Breyer had 87, Ginsberg 96, Souter 90, Kennedy 97 (unanimous), Scalia 98 (unanimous), O'Connor 99 (unanimous), Stevens 98 (unanimous). Back in the middle of the 1900's they'd confirm Justices by voice vote!
Unfortunately, McConnell doesn't care about making this political and the way we are today, Dems will only retaliate if they get the chance. This is who we are now.
